The invention relates to buttons for fastening pieces of cloth togetherand relates more particularly to buttons which may be removably fastenedto a piece of cloth or the like.

Desirable features for buttons of this type include simplicity ofapplication to a piece of cloth, resistance against unwanted removal anddurability and strength, and these features, within certain limitations,are generally found among buttons of this type now in use.

However, these buttons at present usually do not permitl of easy removalonce they are fastened to a piece of cloth, and generally may be removedonly at the price of destruction of the button structure itself. f

It is, therefore, one of the principal objects of the invention toprovide a button which may easily be removed from its attachment to apiece of cloth and may repeatedly be fastened and removed without damageto the button structure.

Another object is the provision of such a button which will firmlyengage a piece of cloth when attached thereto regardless of thethickness of said cloth.

Another object is to provide such a butto which is pleasing inappearance and simple to apply.

A still further object is to provide such a button which may beregulated according to the thickness of the cloth to which itisfastened.

With the above and other objects of the invention in view, the inventionconsists in the novel methods, construction, arrangement and combinationof various devices, elements and parts, as set forth in the claimshereof, certain embodiments of the same being illustrated in theaccompanying drawings and described in the specification.

The foregoing and other objects of the invention will be best understoodfrom the following description of exemplifications thereof, referencebeing had to the accompanying drawings, wherein:

Fig. 1 is an elevational view, partly in section, disclosing a buttonfastened to a piece of cloth, in accordance with my invention,

Fig. 2 is a plan view of the same, and

Fig. 3 is a longitudinal sectional view of a modified button embodiment.

Referring now particularly to Fig. 1, I provide a. button which broadlyconsists of two parts, a male and a female part. The male part comprisesa shaft 2 which is preferably pointed at one end to permit piercingthrough a cloth I for inserting said shaft 2 through the pierced holethereof, said shaft 2 carrying on its other end a flange 3 substantiallyperpendicular to the longitudinal extension of said shaft 2 and adaptedto lie in abutment against one surface of said cloth I when the buttonis fastened to the cloth.

The female part has a disk-like portion 4 which constitutes the buttonportion of the entire device. A hollow sleeve 5 is connected to saiddiskshaped portion 4 about centrally and is preferably integraltherewith and projects perpendicularly therefrom. Said sleeve 5 has anopen end opposite with relation to said disk-shaped portion 4 andcarries there an integral hollow flange 6 around said open end. When thebutton is fastened to said cloth I, said shaft 2 is inserted into theinterior of said sleeve 5 where it fits closely and the male part movedrelative to the female part until the flanges 3 and 6 firmly engage thepart of the cloth I therebetween.

In order to prevent removal of the female part from the male part, Iprovide a bore in said shaft 2, at a point spaced from the flange 3,thereof, said bore extending transversally through said shaft.

Furthermore, I provide in the sleeve 5 of the female part a plurality ofpairs of oppositely disposed apertures 8. Each pair of apertures 8 iscentrally disposed with reference to the central axis of the sleeve andthe apertures of each pair are in alinement, the axis of the alinementbeing transversal with relation to the sleeve 5. Each pair of apertures8 is spaced from the open end of said sleeve 5 for a distance whichvaries for each pair of apertures. The apertures 8 are preferablyarranged along the curve of a screw to permit the differences indistance for each pair of apertures from the open end of the sleeve 5.

Each aperture 8 has the same diameter as the bore within the shaft. Apin 'I may be inserted through one pair of opposite apertures 3 withwhich the bore has been selected to be put in alinement and thereby thefemale part and the male part are interlocked and thus restrained fromrelative movements against each other. I provide a plurality of pairs ofopposite apertures V8 to accommodate various thicknesses of cloth.

When the button is fastened to cloth I the shaft 2 is first insertedthrough the cloth and thereafter the sleeve put over the shaft until theflanges 3 and 6 are closely adjacent the opposite surfaces of the clothI. Then the sleeve is rotated with relation to the shaft until one pairof opposite apertures 8 appears in alinement with the bore of the shaft2. Thereafter, the pin 'I which has a diameter permitting a close fitbetween the alined openings in inserted thereinto.

In order to facilitate the insertion of the pin '1, I provide a long rodof a diameter suitable for close tting into the apertures 8 and the boreand made of wood, plastic or other suitable material. This rodpreferably has circular grooves at spaced intervals throughout itslength, the intervals conforming to the outside diameter of said sleeve5. Thereby, `the long rod may be inserted into the alined openings untilit protrudes to the opposite surface of the sleeve at which point one ofthe grooves will be adjacent the aperture through which the rod wasinserted into the sleeve, and then the rod is broken olf at that groove.This facilitates the correct gauging of the length of against the pin orif the parts are riveted together, by iiling olf the rivet heads andthen expelling the remainder of the rivet.

In the modication shown in Fig, 3 the hollow shaft I0 may consist of ahollow rivet which commonly is provided with a flange.

Since certain changes may be made in the above article and differentembodiments of the invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted aspin 1 without having to resort to great strength V in cutting it fromstock. A l

Instead of making said shaft 2 out of a solid piece of material such assteel or plastic or the like, it may also consist of a hollow cylindermade of sheet metal or of other suitable material. In that case the borewhich has previously been described will not be uninterrupted but willextend through the walls of the hollow shaft only.

In another modication of the invention which is illustrated in Fig. 3 Iprovide a hollow shaft Ill which cooperates with a hollow sleeve I2 toengage a cloth 9. Said sleeve l2 is open at both ends and engages saidcloth 9 with one end and protrudes with its other end into a disc shapedelement I4 to which it may be joined by welding, brazing, or it may berolled thereinto, or otherwise be connected thereto by any othersuitable well known method. This disc I4 is concave and, to provide abetter appearing surface of a button, I provide a cover I5 whichsurmounts said disc I4 to cover the central aperture within said discI4, through which the end of the sleeve has been inserted.

In order to prevent accidental removal of the pin '1 -Figs. 1 and 2-orI3, Fig. 3--from its emplacement transversally within the button, thesurface of thepin is made to fit closely into the openings and haspreferably a roughened surface determined by the selection of thematerial for the same. For instance, if the pin is made of wood, it willbe very difiicult to remove the same from the openings. Should it bedesired to make the connection between the male and the iemale partsstill more permanent, a rivet may replace the pin and the two parts thusbe riveted together.

In order to remove the pin from the button it may be expelled by axialmovement applied illustrative and not in a limited sense.

Having thus described the invention, what I claim as new and desire tobe secured by Letters Patent, is as follows: Y l. A fabric grippingbutton comprising a first hollow cylinder pointed at the one end andprovided with an annular base at the opposite end, a'second hollowcylindrical sleeve adapted to slidingly t over said first cylinder andhaving a button head attached to its one end and means to secure thesaid two cylinders at a dilerent fabric gripping distance.

2. A fabric gripping button comprising a first hollow cylinder pointedat the one end and provided with an annular base at the opposite end, asecond hollow cylindrical sleeve adapted to slidingly fit over saidfirst cylinder and having a button head attached to its one end, saidsecond cylindrical sleeve being provided with a plurality of spirallyarranged oppositely alined aperture pairs and a pin to secure said twocylinders by means of said pin and said aperture pairs at a. differentgripping distance.
